In conclusion whole device stable structure, can prevent wire drawing from occurring so that printer carry out using when beat
The precision of print is higher, prevents spray head from not having to cause spinneret inside jet pipe to knot for a long time, increases the practicability of spray head, have very high
Promotional value.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the shutter partial structural diagram of the utility model.
In figure: 1- protection main body, 2- spray head, 3- guide post, 4- shutter, 5- conveying pipeline, 6- electromagnetic spring, 201- baffle,
301- insulating layer.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Obtained by the spray head 2, electromagnetic spring 6, conveying pipeline 5 of the utility model can be ordered in market or individual.
In the use of the new type: electromagnetic spring 6 (this Electric Applicance Co., Ltd of Shanghai people).
Please refer to Fig. 1~2, in the utility model embodiment, a kind of anti-wire drawing 3D printer printing head, including protection master
